• In accordance with Rule 4, Part 4.05.6(10) of the Rules and Regulations of the Colorado <br />Mined Land Reclamation Board pursuant to the Colorado Surface Coal Mining <br />Reclamation Act 34-33-101 et seq., I, Thomas E. Leidich, state that during construction <br />of Sedimentation Pond 017 inspections were conducted by MWH personal under my <br />supervision. SCC constructed Pond 017 under the supervision of Mr. Roy Karo, <br />Reclamation Manager, and Mr. Dan Allen, Surveyox. Mr. Karo and Mr. Allen ensured <br />that all work was performed in accordance with the design and the specifications. <br />A MWH employee, under my supervision, inspected the structure on a regular basis to <br />verify compaction and to make sure that the embankment was being constructed in <br />accordance with Rule 4, Part 4.05.6(10). My self and/or Jay James (MWH) were also on <br />the site at several critical occasions during the construction of this pond, as well. MWH <br />summary of compaction testing for this project is located in Addendum 13-SH-D <br />The purpose of my inspection and certification was to make sure proper construction of <br />Sedimentation Pond 017 and to satisfy the requirements of Rule 4.05.6(10) of the <br />• Colorado Mined Land Reclamation Board. The material was placed in the embankment <br />to meet or exceed the design specifications (see Addendum 13-5H-E for Geotechnical <br />Report). This as-built report confirms the construction of this structure meets or exceeds <br />the Rules and Regulations of the Colorado Mined Land Reclamation Board. The <br />structure is stable, evidencing no indications of slope instability. <br />To the best of my knowledge, based upon my professional expertise, and to the extent <br />possible, Pond 017 at the II-W Mine was constructed in accordance with the prudent <br />state-of-the-art methods for earthen embankment construction. Further, the suucture <br />was constructed in compliance with the approved design, to the extent possible, as <br />specified in Attachment 13-SB, Drainage and Sediment Control Plan, of SCC's approved <br />mine permit. <br />r1 <br />LJ <br />13-5H-3 <br />
